History of Curly Hair Care Product Development
and Current State of the Art

Back in 1986, Lancôme and Dior simultaneously launched the first nanotechnology-based cosmetic products. Today, many cosmetic products use nanotechnology in local skincare products with the goal of improving function, modifying appearance, and prolonging their shelf-life.


The rapid rise of the cosmetics industry has been characterized by a growing demand for innovative products designed using the science of nanotechnology.

In the 1990s, celebrity stylist Andre Walker introduced his Hair Typing SystemTM on the Oprah Winfrey Show. This system divides hair into four types: straight, wavy, curly, and coily, depending on curl pattern, with subcategories a-c.

In 2005, L'Oréal research indicated that “hair curliness is programmed from the bulb region of the hair follicle” and curliness is linked to asymmetry in different parts of the hair follicle. Curly and coily hair follicles are characterized by having a curved dermal implantation where it meets the skin dermis at an acute angle forming a golf club shape. They concluded that these manifestations represent stress on the hair follicle.


In 2012, Robbins and Clarence explained why hair shafts curl; they suggested that the coily hair is a functional response to the need of our human ancestors living in the intense ultraviolet radiation of the sun in Africa. They claim that coily hair functions as part of the body-temperature-regulating system.


 The anatomy of the hair follicle: The Arrector Pili muscle

Do we know the “Arrector Pili” muscle? Yes, we do!

The Arrector Pili muscle is the real cause behind goosebumps.


Anatomically, it is the tiny smooth muscle that connects the hair follicle to the epidermis. When the body is cold, the arrector pili muscle contracts all at once, causing the hair to “stand up straight” on the skin forming goosebumps.

Arrector Pili is innervated by the autonomic nervous system, which handles unconscious tasks.

Arrector Pili has additional functions? In 2020 Harvard scientists found that Arrector Pili muscle and its nerves have the function of controlling hair growth.

We are bringing this tiny muscle to light as a major player in shaping coily and kinky hair! We develop "CurlRelax™", the first oral supplement that gets to the root cause of curly/coily and kinky hair by relaxing the muscle of the hair follicle to promote the growth of straight, natural-looking hair women love.
